Coulombic inter-actions, hydrogen bonding and supra-molecular chirality in pyridinium trifluoro-methane-sulfonate

Research output: Contribution to journalArticlepeer-review

Abstract

The title compound, C5H6N+·CF 3SO3 -, was serendipitously crystallized in the chiral space group P43212. The component entities associate into hydrogen-bonded helical chains, which propagate along the a and b axes of the crystal, with an alternating disposition of the cations and anions along the chain. N - H⋯O charge-assisted hydrogen bonds, from each pyridinium cation to two adjacent trifluoro-methane-sulfonate anions and from every anion to two different cations, direct the formation of the supra-molecular chiral arrays. The crystal packing exhibits nonconventional C - H⋯O and C - H⋯F hydrogen bonds between the components. The observed structure demonstrates induction of supra-molecular chirality by a combination of Coulombic attractions and inter-molecular hydrogen bonds.
